RAILWAY-CAR TRUCK.

Specification of Letters Patent.

Patented July 3, I908 u Application and September 7, 1&505. Serial No. 27?,434.

columns of pressed or rolled metal, preferably steel or wrought-iron, to replace the cast ones, and cooperating with these pressed or rolled columns'I use base-blocks and caps recessed to receive the bottom or inverted and top arch-bars, respectively. In my novel truck I also employ an improved type of springplank, which is depressed at its central portion, thus permittin the use of a wide 'and deep bellied truckboIste1-, the springplank being preferably made up of end and central rolled or pressed sections riveted toether, the central section acting as a spacer or the inverted arch-bar and bottom tie-bar. The rivets which unite the sections of the spring-plank also pass through andv hold in p ace the brake-hangers.

In the accompanying drawings I have illustrated a practical form of my invention, like reference characters on all the figures referring to the same arts.

Figure 1 is a p an VifiW of a car-truck-embodying my invention. Fig. 2 is a side view of the truck shown in Fig. 1, the wheels being indicated by dotted lines and the journalboxes being entirely omitted. Fig. 3 is a partial elevation and a partial section illustrating the adaptability of the truck to a deep-bellied truck-bolster and showing also the body-bolster. Fig. 4 is a perspective view of the cap used atthc top end of the column. Fig. 5is aperspective view of aportion of the parts constituting the side frame and spring-plank of the truck. Fig. 6 shows in perspective the base-block used. at the bottom of the column; and Fig. 7 is a cross-section of the spring-plank, showing the brakehanger in elevation.

Referring first to Fig. 3, 10 represents any usual type of body-bolster, the same being supplied on its lower edge with a centerbearing plate 11 and side bearings 12. Beneath this body-bolster is a bellied truckbolster 18, which has on its upper surface center-bearing plate 14, cooperating with plate 11 of bolster 10, and SICB bearings 15,

acting in conjunction with side bearings 12 of o the body-bolster. The side frame of the cartruck comprises the top arch-bar 16, the inverted or bottom arch-bar 17 and the bottom tie-bar 18, the ends of truck-bolster 13 extendin between and beyond the columns of the side frames. The two side frames of the t are spaced apart and tied together by a novel form of springlanlr, which has end channel portions 19, wit. their flanges ex tended upwardly, and a central channel-section 20, which has its flanges extended down wardly, the central channel being riveted to the inner ends of the end channel-sections, the rivets also passing through and holding in place brake-hangers 21, which rest in the troughs of channels 19. This construction, which includes a depressed or lowered central part of the spring-plank, allows the use of a deeper and wider truck-bolster than has been usual without sacrificing the strength and bending resistance of the spring-plank.

Central cl1annel-section 20 is of such a length that its ends abut against and space apart the bottom tie-bars l8'and the invert ed arch-bars 17. Nooden spring-blocks 22 rest in the end channel-sections 19 the lower ends of springs 23 pressing against the wooden blocks, the upper ends of the springs sustaining the truck-bolster 13, Whj ch is supplied on its sides with guides 24, adapted to cooperate and slide upon the columns to be described.

Instead of the usual cast-metal columns I employ columns made of two pressed or rolled members, the inner plate member 25 of each column, which has parallel longitudinal edges for the greater portion of its length, being provided at its lower end with edgewiseprojecting cars 26, which permit the passage of bolts 27' through perforations end of each column there is provided a cap of the type shown in Fig. 4, which has a stem 31, ada ted to lit within the hollow rib 29 of the 008mm, the upper surface of the cap being countersunk at 32 toreceive the top arch bar, a perforation 33 passing through the entire cap, for a purpose to'be.

explained below. At theiower end of each column there is [supplied a base-block 34 of the shape illustrated in F ig'. 6, the block having perforated cars 35, through which bolts 27 pass to hold the same in place againstthe column. The upper surface of'block 34 has a recess 36, adapted to fit about the lower end' of rib 29, and also has a rojection 37,

adapted to fit in the lower en of the hollow rib. To keep the inverted -arch-bar 17 in place, the bottom and end inclined surfaces of base-block 34 are countersunk at 3i8,"the block also being provided with a perforation 39, passing completely through the block, in-

. eluding projection 37.

- the top arch-bars.

' Minor mechanical changes may be made in.
